Issue clergyman raised, given nothing initially for extra work (8)
I believe the answer is:
overtime
'extra work' is the definition.
(I've seen this before)
'issue clergyman raised given nothing initially' is the wordplay.
'issue' becomes 'emit' (both can mean to give out or radiate).
'clergyman' becomes 'rev' (short for reverend).
'raised' is a reversal indicator (going up in a down clue).
'given nothing' becomes 'o' (looks like zero - 0. I am not sure about the 'given' bit.).
'initially' says to put letters next to each other (some letters go before others).
'emit'+'rev'='emitrev'
'emitrev' back-to-front is 'vertime'.
'vertime' after 'o' is 'OVERTIME'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for overtime that I've seen before include "opportunity for supplementing income" , "Extra hours worked" , "Work outside normal hours" , "Hours worked and paid for beyond the usual amount" , "Pay for extra work" .)
